     package layar;

     import java.io.*;

      public class easyTesting 
      {
        public  void startCode()  
        {
         File f = new File("layertestnew.php");
          if(!f.exists())
          {
              f.createNewFile();
          }
          else 
          {
            f.delete();
          }
        }

        }

      </head>
      <jsp:useBean id="link" class = "layar.Testing" />
      <body>
      <form action="poi.jsp" method="post">
      <INPUT type="button" value="Create script file" onClick = <%
  link.startCode(); %> "window.location.reload()"><br>
